I finally decided to build my very own battery operated GPS device. So I started designing the PCB and i am having hard time understanding certain things.
Here are the details of the board
Contains GPS receiver and Bluetooth 4.1
Battery Management unit ( with charging current of 2A )
A Buck-Boost Converter ( 1.6Mhz, ILmax= 1.2A)
Controller with 32Mhz Crystal
How do I decide if I need a Polygon pour? Should the poly always be ground? How does poly affect the performance of the GPS or BLE?
